Breathing Life: How Air Quality and CO₂ Impact Our Health and the Environment

Without a doubt, the quality of the air we breathe is a key factor in our health and well-being. In this regard, the growing pollution has put this precious natural resource under pressure. This has led governments and organizations to take action to raise awareness and implement measures aimed at preserving air purity.

Good Quality Air: What Is It and How to Measure Air Quality?

Air is a vital element for human survival and that of the rest of the planet, but how do we know if it is of good quality? The European Environment Agency uses an index called the ICA, which allows us to know the state of the air anywhere in the world.

This system is based on measurements of the most harmful air pollutants for health and the environment (fine particles, ozone, carbon monoxide, nitrogen dioxide, and sulfur dioxide). In this way, it provides an indication of the quality of the air on a scale from 0 to 500:

• Good (0 to 50): The air is optimal.
• Moderate (51 to 100): Little or no risk to health.
• Unhealthy for Sensitive Groups (101 to 150): Has negative effects on the health of children, the elderly, and people with respiratory or cardiac diseases.
• Unhealthy (151 to 200): It is harmful to all people.
• Very Unhealthy (201 to 300): Breathing this air is dangerous, so outdoor activities are recommended to be avoided.
• Hazardous (over 300): It is not advised to go outside without a mask.

How Poor Air Quality Impacts Health

As air pollution levels rise, so does the risk of diseases (eye irritation, cough, asthma, bronchitis, heart diseases...). According to data from the WHO, it is estimated that around 6.7 million premature deaths occur worldwide each year due to the harmful effects of air pollution.

Environmental Impact of Poor Air Quality

Poor air quality not only impacts human health but also has serious consequences for our environment. Firstly, many pollutants, such as carbon dioxide, methane, and nitrogen oxide, are greenhouse gases that trap heat in the atmosphere, which contributes to global warming and accelerates climate change.

Furthermore, we must not forget that pollution present in the air can be deposited into soils and surface and groundwater through precipitation and dry deposition. This has negative effects on agriculture, fishing, and wildlife.

Controlled Mechanical Ventilation Systems

A controlled mechanical ventilation system is a great ally in improving the quality of the air indoors in buildings, as it ensures proper circulation of fresh air inside.

In this way, it reduces the concentration of pollutants, such as carbon dioxide, volatile organic compounds, allergens, viruses, and bacteria. It also combats humidity and prevents the growth of mold and fungi, which in turn can prevent respiratory problems and allergies.

The quality of the air is a topic of growing global concern. Fortunately, innovations and new technologies come to our rescue with efficient solutions like ventilation systems.
